The drink: Aloha Pineapple Smoothie (Make it Light)The extras: Flax & Fiber Boost, Probiotic Boost, Whey Protein BoostThe reasons: At 190 calories, this drink is just right for a satisfying snack, which should ring in at 200 calories or less. While smoothies can be high in carbohydrates and low in protein, these extra boosts will add the necessary fiber, healthy fats, and protein to help stabilize blood sugar levels and keep you energized for longer.

The drink: Apple 'n Greens SmoothieThe extras: Two Whey Protein Boosts, Probiotic BoostThe reasons: The simple ingredients list includes a green juice blend (carrots, spinach, bell pepper, kale, spirulina, and lettuce) along with peaches, mangos, bananas, and ice. You do get a big dose of carbs (50g), but that can be really useful after a workout—they help deliver protein to your muscle cells. Plus, the whey protein boosts (20g protein) help put those carbs to good use, while the probiotics build gut health.

The drink: Banana Berry Smoothie (Make it Light, 16-ounce)The reasons: If you’re on the go and need a quick snack, this drink is a healthy choice. Made with 100 percent whole fruit and fruit juice, it packs only 170 calories (1/3 less than the original), with ample fiber (3g) and protein (5g) to keep hunger at bay.

The drink: Orange Apple Pineapple Ginger JuiceThe reasons: This is a great snack for people on the go, or for anyone seeking a post-workout boost. The fruits deliver a huge dose of vitamin C (240 percent of your daily value), which protects cells by neutralizing free radicals. The ginger speeds up exercise recovery and may even reduce muscle soreness, helping you feel ready faster for your next workout. I recommend the 12-ounce version, which delivers all these benefits for only 170 calories.

The drink: Orange Carrot Karma SmoothieThe reasons: This provides both fruits and veggies (which many people don’t get enough of in their diet) in one serving. The 16-ounce size combines carrot juice with real fruit (banana and mango) and 100% fruit juice (orange juice). The drink is loaded with vitamin A, is an excellent source of vitamin C, and provides a good source of fiber. It also has a little bit of protein. This smoothie also is relatively low in sodium (only 90mg) compared to most packaged snacks. It also provides a good dose of potassium, a mineral that many fall short on. Have this smoothie with a handful of nuts for a protein- and fiber-rich mini meal that's satisfying and energizing.

The drink: Berry UpBEET SmoothieThe extras: Whey Protein BoostThe reasons: This smoothie has less sugar than most of the all-fruit smoothies with only 38g for the small. The 8g of fiber help you feel satiated. Plus it's soy-free! The only downside to this snack is that there's almost no fat, so if you make this your on-the-go choice, be sure to get plenty of good fats during the rest of your day.

The drink: Tropical Harvest (16-ounce)The extras: Double Greek Yogurt BoostThe reasons: For 280 calories (230 for the smoothie and 50 in the double boost), I get a ton of vitamins A and C, thanks to the orange veggies (sweet potato, carrot, butternut squash) and fruits (mango and peach). Those nutrients are particularly helpful at this time of year for fighting colds and flu. Plus, this drink provides 10g of protein to keep me full, and supplies 16 percent of the daily value for calcium. The live active cultures are beneficial for digestion, too.

The drink: Kale Apple Pineapple Chia Seeds Juice (12-ounce)The extras: Soy Protein BoostThe reasons: This is a smart choice because this combination gives you vitamins, fiber, and plant protein. Kale, a superfood, is chockfull of vitamins A and C, while chia seeds provide 3g of fiber and healthy fats. The sugar comes from fresh fruit and provides quick energy plus nutrients, while the 3g protein and 4g fiber help you stay full for a few hours.

The drink: Make-Your-OwnThe extras: Whey or Soy Protein Boost, Chia Seed BoostThe reasons: I’ll ask (politely!) to make my own smoothie to cut down on calories and sugar. First, request water as the base—no sugary juice, yogurt, or sherbet. (If you prefer, go with half water, half almond milk or soymilk.) Then add a small amount of raspberries, strawberries, blueberries, and half a banana for potassium. Ask for two servings of the whey or soy protein boost, since each one only offers about 10g protein. Finally, add a chia seed boost for an extra dose of fiber and omega-3s. Don’t be afraid to speak up for a slimmer but still delicious smoothie!
